EXPLGSIVE.

factured and handled without danger of explosion, and one that will retain its strength for any length of time if kept dry. These objects I accomplish by the proportionate mixture of the following ingredients.

I use granulated sugar 25%, and enough water to dissolve it. This mixture is boiled until it forms a syrup which will harden when cooled. Then remove from the heat and stir into this syrup powdered chlorate of potash 30%. When the mass is stirred until it is of the consistency of soft putty it is granulated by rubbing it through a screen having a mesh of the size of the grains desired in the finished product. When thoroughly dried, mix with this granulated .mixture of sugar 25%,

charcoal 15%, black mass, the following powdered ingredients: charcoal 15%, black dioxid of manganese 15%, sugar of milk and zinc dust The zinc dust is sometimes called zinc fumes and is largely produced at zinc'smelters.

This explosive may be fired 'by an electric battery or the common fuse without using a cap, and its explosive force is the greatest in an upward and outward direction.

Having thus described my invention I desire to secure by Letters Patent and claim:

1. An explosive consisting of a granulated mixture of sugar and chlorate of potash mixed with powdered charcoal 15%, black dioxid of manganese 15%, sugar of milk 5% and zinc dust 10%.

2. An explosive consisting of a granulated and powdered chlorate ofpotash 30%, mixed with powdered 15%, sugar of milk 5%, and zinc flue dust 10%.

In testimony whereof I have. aiiixed my signature in resence of two witnesses.
